Answer Posted / Navaneet Kumar
Blister in box girder bridge refers to a localized defect or damage that occurs on the concrete surface of the deck. It appears as a raised, bubble-like area due to the buildup of air or moisture beneath the concrete surface. The primary function of a box girder bridge is to support the load and transfer it from one side to another while providing clearance for the passage of vehicles or other traffic. In the context of blisters, they can compromise the structural integrity and durability of the bridge if not properly addressed.
